WASTE-VALVE MECHANISM.

Application illed Gctober 1B, 1924. Serial No. 744,806.

To all whom @t may concern.'

Be it known that l, HERMAN W. Kimm.,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Waste-Valve Mechan nism, of which the following is a specification.

This invention relates to a waste valve l0 such as may be employed advantageously with bath tubs, lavatories, etc., and is particularly concerned with an operatin mechanism therefor which may be readily installed or removed.

The embodiment of my invention set forth in the accompanying drawings and in the description to follow is especially suited for use with plumbin i fixtures of the kind which are employe with built-in bath tubs.

20 With such installations, accessibility to the operatin parts of a waste valve is greatly reduced 1n conse uence of which there is an increased need or an o erating assembly which may be convenient y installed or re- 95 moved. It is largely to meet such conditions that the present invention has been designed, the objects and urposes served thereby being set forth fu ly in the specification and claims to follow, taken in conjunction with 30 the accompanying drawing wherein- Figure' 1 is a vertical section through one end of a tub, together with fittings which constitute the overflow and waste outlets therefrom;

Fig. 2 is a similar view on a reduced scale showing the valve operating partsn process of installation or removal; and

Fig. 3 which is a detail in perspective shows the adjacent ends of two elements 40 forming part of the linkage for operating the waste valve.

Referring now to the drawin in detail in all of which like letters an numerals in the usual manner as by means of an over- 5 low L 6 having a lian 7 which bears against the outerface of t e tub wall. Connected with this L as by screws 8 is an apertured plate 9 which bears against the inner face of the tub wall, a suitable gasket or packing being interposed to prevent leakage. This plate carries a bearing 10 in which is mounted for rotation a stem 11 having an operating handle 12 at one end thereof.

The lower end of the overflow tube is con? nected with a T-fitting 15 with which is also connected a pipe 16 leading to the tra (not shown). By this arrangement the pipe 16 may be aligned with lthe over-flow tube. Connected also with the T, so as to extend laterally from the overflow tube2 is a. waste arm 17 which has connection wlth a waste shoe 18wherein is mounted a pop-up valve 19. The waste shoe may have threaded connection with a cage 20, the head of which is shown as flush with the inner face of the tub wall adjacent its bottom. Depending centrally within the cage is a stem 21 slidably received within a `sleeve 22 which upstands from the waste valve. Also guidin ribs 23 may depend from the valve, as s own, to cooperate with the surrounding walls of the valve seat so as to assure a proper up and down movement of the valve.

The mechanism by which the present valve is operated comprises a two-unit linkage of peculiar formation. Included in the first unit in this linkage is a crank arm 24 carried by the rotatable stem 11, a pin 25 extending laterally therefrom, a link 26 connected to the pin and to a head 27 which is adjustably mounted on the upper end of an arm 28, wherein may be formed a slight bend as shown. The lower end of this arm has a pivotal connection as at 29 with a second arm 30 wherein may also be formed a bend similar to that in the arm 28, there bein adjustably mounted at the lower end of t e arm 30, a foot 31 ot appreciable weight. The link 26 and the two arms 28 and 30 which de end from the crank arm 24 are unsupporte within the overflow tube, but because of its vertical disposition and the size to which the several parts may be formed, the foot 31 is held a ainst any extended lateral movement. e perforated plate 9, together with the stem 11 and operating parts suspended therefrom, constitute one unit in the operating linkage for the present waste valve.

A second linkage unit is disposed within the waste arm 17 and shoe 18.- This comprises, by preference, a lever which is formed of three stems 35, 36, and 37 extended in straight-line relation and pivotally connected together as at 38 and 39. Depending rfrom the intermediate stem 36 is a pin or By some such connection as this, the lever is twice foldable in one direction, but not the other. One end of the rocking lever is formed with a seat whereon may be the foot 31. At the o posite lever end, a connection is made wit atongue 46 which depends from the waste valve 19. This last connection completes they linka between the Waste valve and the associated parts which constitute the second unit in the oper ating mechanism.

In the use of the resent valve, it is necessa merely that t e handle 12 be turned to raise the foot 31.` 'Iliis rotation may continue through 180` at which point the link 26 will engage lwith the stem 11 to;A arrest further movement. In this position theV crank arm is in a dead center position so as.

to sustain indefinite] the parts whichr de pend therefrom. With lifting of the foot 31 the rocking lever is also moved in respouse to the weight of the valve 19 upon t e stem 37. When this takes place, the valve is permitted to drop into its seat, thus shutting oi communication from the tub to the waste outlet. The valve may be`raised however, by a- Areverse movement of the handle 12 whereupon the foot 31 in its operative relation to the rocking lever again over-balances the valve to thereby eiect a lift of the latter. In either position of operation it will be noted that communication between the tub and overflow tube is preserved.

The mechanism herein described is particularly advantageous, in that it may be readily removed from the waste pi in which it is installed for operation. o accomplish this the plate 9 is disconnected from the L 6 whereu n the first unit of the lintlage may be wit drawn in the manner indica in Fig. 2. The valve cage which is also dsconnectable from the shoe 18, permits the valve and parts formin the second unit, to be removed, as s own. It is important to note that between the two units in the li system there is no connection whatever, o y a loose contact of the foot 31 upon the seat 45. For this reason follows that either unit may be removed or re-in-YV stalled independently of the other.

The arts forming the present-invention` are suc as may be reduced at small expense and are not lia le to get out of order. At the same time, as is found to be the case with all plumbing fixtures, provision must be made for tting at the valve parts, in case it shouldecome necessary to clean out the waste pipe or for any other purpose. It

is for these reasons that the present conthe i waste outlets, means connecting said outlets f with a source of waste disposal,` a valve mounted adjacent one outlet, an operating member adjacent the other, and a linkage system comprising two units, one conn with the valve and the other with the oeratiiig member, eac'h adapted for inde ent installation or removal, and having a loose but operative en gement with the other, substantial] as ilscribed.

3. In combination with a receptacle having waste and overflow outlets, means connecting said outlets with a source of waste dis sal, a valve for contro the p able ever to one end of which the valve is secured, and a foldable linkage unit adaptof i uid through the waste outlet, "a foldspewing A ed to engage with the opposite lever and movable into and out vof .positionl through the overow outlet, substantially as described. y

5. In combination with a receptacle having waste and overflow outlets, a waste shoe arranged adjacent to the former a valve movable within the shoe to control the passage of liquid therethrough, an L adjacent to the overflow outlet, an overflow tube connected with the L and with a vsource of waste disposal a waste arm conlie with the waste' necting the overflow tu shoe, a plate detachably connected to the overflow L, a stem rotatably journaledV in the plate, means 'for operating the stem, a cram arm carried by the stem, a link con- ,nected with the crank arm, a pair of intersuch that the atter is reciprocated in resecured sponse to movements of the vWeighted foot, tie two linkage units being independently movable into and out of operative position, substantially as described.
